. COLLAPSIBLE BED.

Application filed January 25, 1922. Serial No. 531,585.

My invention has reference more particu larly to abed structurecomprising two sections, which may be nested. one within the other toform a single bed or davenport, or may be extended to afl'ord a doublebed, or completely separated, thus fornnng twin beds.

Beds of this type heretofore have had the movable section arranged toslide under the mattress supporting surface, or spring frame of thestationary section, and as the mattress was usually doubled over on thestationary section toward the side from which the movable section iswithdrawn, it was necessary to lift the entire mattress in order to foldor unfold same. Moreover a flounce or drape is usually provided on themattress to hang down along the ends and outer SlClGOf the collapsedbed, and in previous structures thls was in the way and liable to becomecaught in the moving parts and had to be stralghtened out each time thebed was extended or collapsed. It has also been the prevlous practice toprovide supporting legs for the movable section only at the outer side,the inner side being slidably mounted on the stationary section.

In my construction the upper section 18 movable so that the doubledovermattress is pulled out with this section, and it is merely necessaryto lay the top fold of the mattress back over the stationary section inextending the bed, and vice versa in collapsing the structure, thusavoiding the necessity of lifting the entire mattress as in pre viousbed structures of asimilar character.

Moreover as the fiounce is attached to the lower fold of the mattresswhich latter moves with the movable section. the fiounce is notdisturbed by the extending or collapsing of the bed structure, nor bythe folding and unfolding of the mattress, and there is also no dangerof the fiounce becoming caught in the moving parts.

Another important feature of my construction is that neither of mySections depend upon the other for support, but each is constructed inthe form of a complete selfsupporting cot which interlocks with theother to form the extensible bed but maybe readily separated and usedindependently as a separate cot.

Other features or objects of my invention have to do with facilities forinsuring direct in and out movement of the movable section 1 and thereso that the latter may be grasped atany point and. easily adjust-edwithout danger of cramping or. binding between the sections,

are also other features of improvement embodied in my invention whichwill appear from the following detailed description thereof.

Fig. 15, asection view on the line 15-15 the angle iron being notched atthe juncture I of the legs 3 with the intern'iediate portion 6 to effectthe bond and afford. a iuitre fit. A corner brace 7 connects each legwith the intermediate portions 6 as shown.

The side rails 4 which are preferably of angle iron are positioned asuflicient dis ,t-ance below the upper ends of the legs 3 so as toafford ample clearance below the spring structure 8 which extendsbetween the intermediate or top portions 6 of the end frames and thereare corner braces 9 between the side rails and legs 3 as shown. Thespring structure 8 which supports the mattress is preferably of woven orlink wire fabric and has a number of helicals 10 at each end connectedwith the top portion 6 of the corresponding end frame to hold the springstructure under the required tension, and in order to brace the endframes against the strain of the spring structure and the supportedweight, the brace rods or bars 5 are positioned well below the siderails at, substantially as shown.

The section 1 of the bed is sufficiently smaller in length and height tonest within the section 2 and is combined therewith by inserting thelegs 3 at one side of the section 1 between the spring structure 8 andside rail at of the section 2 as shown in Fig. 8, so that the sectionsare adjustable for extending and collapsing the bed, and are interlockedso as to prevent scpartion thereof when the bed is extended.

The section 1 which remains stationary is preferably provided with knobs11 instead of casters on the lower ends of the legs 3 so that itwill notmove easily. The other section 2 is preferably mounted on bed ends 12which serve to enhance the appearance of the bed and afford arm restswhen the strutcure is collapsed to couch or davenport form. The marginalframe of these bed ends comprises side posts 13 which correspond to thelegs 3 of the section 2 and are secured to the latter by bolts 14 orother suitable fastenings and project below said legs so as to supportthe section 2 at the proper elevation. This construction renders itpossible to convert the section 2 into an ordinary cot by merelyremoving the bed ends 12, or a standard cot structure may be utilized inmaking the bed by merely attaching the bed ends 12 thereto. The posts 13are supported by rollers 15 which do not have a caster mounting but areheld in a fixed position in line with the required direction of movementof the section 2 or their axes of rotation remain always parallel withthe length direction of the bed so that they serve to eifectivly guidethe movement of this section and avoid cramping or binding which occurswhen the usual caster wheels are employed. These wheels or rollers 15may be mounted on the posts 13 in any suitable manner, as for example asshown in Figs. 13, 1 1 and 15, wherein the yoke 16 has the wheel orroller 15 journaled on a stem or pin 17 which extends between andconnects the arms of the yoke and the intermediate portion of the yokeis inserted into the lower end of the post 13 and secured therein by therivet 18 or other suitable fastening.

It is not necessary to use any bed ends or arm rests on the section 2 asthe latter may,

if desired, have the legs long enough to support the spring structure 8at the re quired elevation and the rollers 15 mounted directly on thelower ends of the legs 3. Arm rests can be provided on this structure asshown at 19 in Fig. 4: wherein a short frame is secured to the upperends of the legs 3.

For the purpose of further insuring the necessary direct in and outmovement of the section 2, I have provided a pair of guide straps 20 and21 at each end of the section 2, and between which the legs 3 of thesection 1 are confined. These guide straps extend between the side rails4 of the section 2 and the former may be permanently attached to theside rails. The guide strap 21, however, is preferably pivoted to theupper flange of the inner side rail 4;, as indicated at 22, so that whenthe outer end is released it may be swung as indicated by the dottedlines 23 to a position directly over the side rail 4, thereby renderingit possible to disconnect or separate the sections 1 and 2 withoutdifliculty when it is desired to use them separately as individual cots.To this end the outer ends of the guide straps 21 are preferably securedto the side rail 4 by bolts 24 or other detachable fastenings, so thatthese guide straps may be swung out of the way whenever the occasion mayrequire.

A mattress 25 of suitable width to extend over both sections 1 and 2when the latter are opened out to the full width is provided, and whenthe bed structure is contracted or collapsed, the portion of themattress lying over the section 1 is merely folded over on top of theportion of the section 2, as indicated by dotted lines at 26 in Fig. 9.This mattress preferably has a flounceor drape 27 which hangs down alongthe outer side of the section 2, and there may also be end portions 28of the flounce or drape preferably separate from the portion 27 so as tofit down between the section 2 and the bed end 12 thereon. WVith thisconstruction it will be observed that the lifting of the mattress incollapsing or extending the bed is not only avoided as it is merelynecessary to fold half of the mattress to the position shown by dottedlines at 26, or to the position shown in full lines. but moreover as theflounce or drape extends down around the movable section 2 it is not inanyway disturbed in open ing or closing thebed and there is nopossibility that it may become caught in moving parts, as in bedstructures of this character which have been provided heretofore.

The bed end 12 at one end of the section 2 may serve as a pillow restand to provide a pillow rest for the other section 1 a wire ill) frame29 is pivoted to the top portion 6 of by full lines.

After a bed has been used for some time the spring tension on the springstructure 8 some times becomes relaxed and as the spring structure 8 ofthe section 1 slides under the spring structure 8of the section 2 inrather close proximity thereto, it is possible that the spring structureof the section 2 might sag sufficiently to catch on the spring structureof the section 1. To avoid contact between the sprin structures andfacilitate the sliding relative movement thereof, a pair of straps 30are extended across under the spring structure 8 of the bed section 2 atsuitable intervals and have the outer ends connected to opposite sidesof the spring structure 8 so as to serve as guides which slide overtheupper surface of the springs 8 on the section 1.

lVith the construction as above described, having the rollers on themovable section arranged to confine the movement of the latter to adirect in and out movement, and also having the guide straps 20 and 21,it is not necessary to grasp the section 2 intermediate of the ends foroperating same so as to avoid binding as in previous structures, but thesection may be readily operated Without binding by applying the requiredpressure at the ends of the section or any other point.

In the description of my invention and particularly in the followingclaims, I use the terms stationary and movable to dis tinguish thesections,-not intending, of course, that the one section is incapable ofmovement, but to signify that the so-called movable section is the onewhich is designed and intended to be moved or adjusted in extending orcollapsing the bed structure and that the so-called stationary sectionis de signed and intended to remain stationary while the other sectionis adjusted.

While I have shown and described my in vention in a preferred form, I amaware that various changes and modifications may be made Withoutdeparting from the principles of my invention, the scope of which shouldbe determined by reference to thefollowing claims.
